... have you guys ever resized a photo before?

you can't just change the dimensions either. design software can't change the size of a pixel on screen, so it changes the scale of the inch instead, which is why a 300dpi image is 3x as big as it seems.

if you go to view>print size in photoshop, it'll zoom out to the proper 1:1 ratio and show you how big the image will print. if you change the document dimensions, you'll reduce size, because you'll be changing the overall size of the document. it can still be 300 dpi, but it's going to print 4" to small if you change the canvas size from 6x12 to 4x8.

if you're working with print or large format, you're stuck working with large files.
